Resilience and disaster recovery in Amazon Keyspaces
The Amazon global infrastructure is built around Amazon Web Services Regions and Availability Zones. Amazon Web Services Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.
Amazon Keyspaces replicates data automatically three times in multiple Amazon Availability Zones within the same Amazon Web Services Region for durability and high availability.
For more information about Amazon Web Services Regions and Availability Zones, see Amazon global
infrastructure
In addition to the Amazon global infrastructure, Amazon Keyspaces offers several features to help support your data resiliency and backup needs.
- Multi-Region Replication
-
Amazon Keyspaces provides Multi-Region Replication if you need to replicate your data or applications over greater geographic distances. You can replicate your Amazon Keyspaces tables across up to six different Amazon Web Services Regions of your choice. For more information, see Multi-Region Replication for Amazon Keyspaces (for Apache Cassandra).
- Point-in-time recovery (PITR)
PITR helps protect your Amazon Keyspaces tables from accidental write or delete operations by providing you continuous backups of your table data. For more information, see Point-in-time recovery for Amazon Keyspaces.
